Disable failing tests on Linux GPU FYI Exp Intel 630 and TSAN bots

The following tests are being disabled on the experimental
Intel 630 bot:
1) angle_end2end_tests since the failures are numerous to exclude
   individually.
2) tab_capture_end2end_tests since the test suite consists of 2 tests
   and one of them fails.
3) vulkan_content_browsertests since the test suite consists of 3 tests
   and all fail.

vulkan_content_browsertests also flakes on Linux FYI GPU TSAN Release
and is being disabled there as well.
